Title: Electric joint box
Inventor: OTA HIROAKI
IPC: H02G3/14
Filed: 1993-07-13
Abstract: PURPOSE:To enhance sealing performance without using any rubber packing by a simple structure where the gap between the cover and the box body is eliminated through grinding of inclining faces. CONSTITUTION:An inclining face 22 is formed on the end face of a protrusion 20 provided at the end of the side wall 1a of a box body 1. An inclining face 24 abutting on the inclining face 22 is formed on the inner side face of the outer side wall 10b at a recess 10 in a cover 3. The inclining face 24 is formed steeper than the inclining face 22. When the end of the side wall 1a is inserted into the recess 10, the inclining face 22 abuts at first, at the lower end thereof, on the inclining face 24 which is then pushed to the outside by the inclining face 22 thus opening the wall 11b outward and bringing the inclining faces 22, 24 into tight contact. The side wall 1a is brought, at the forward end face thereof, into tight contact with the rear wall of the recess 10 thus ensuring the sealing performance. Since the inclining faces 22, 24 are brought into tight contact while imparting force to each other, backlash is eliminated in the inserting direction and the direction perpendicular thereto and the sealing performance is sustained positively.
